I have bought this old Neumann 8x2 mixer, seventies made i think
I am still waiting for the delivery, so I don't know yet how the desk is exactly configured.
Please note that - sadly - the eq modules had been removed and sold prior to my purchase.
The main channels have 8x PV-46-B modules.
There are other 5 line modules nearer the master section, but I can't understand what they are. I suspect PV-15 but I'm not sure.
One thing I'm afraid is that this desk might be commissioned from a broadcast station, so probably the output level is not optimal for interfacing with other equipment ??
First thing I'm planning to do, adding as much line inputs as can fit in the frame.
But I am already a bit confused because there are 3 different versions of the PV-46 line amp !
- PV-46-B present in the consol are actually called "compensation amplifier" on the schematic
- PV-46-SD is very similar to the B version but there is some small changes in the circuit
- PV-46-D is the latest version, it's dual channel, uses different transformers and runs OA10 discrete opamps instead of plain transistors as the B and SD versions
I already have a spare PV-46-D module and have opportunity to buy a few PV-46-SD. The only thing I'm concerned about, is because the other channels in the console are using PV-46-B modules, there could be any compatibility issues regarding impedance and levels mismatch between the different versions ?
If this is not the case, it would be great, different sounding channels could be useful to differentiate separate tracks / stems
After I'll have sorted out the configuration of the channels, will think about adding a couple of aux channels, headphone amp, some switching, etc..
Looking forward to getting all kinds of ideas and recommendations for this project !!
All the best fellas
